MACHINE FOR INSERTING PINS 0R RIVETS IN UMBRELLA-FRAMES.

SPECIFICATION forming W of Letters Patent No. 282,668, dated August 7,1883.,

Application filed June 28, 1882. (No model d 7 To all whom it mayconcern:

and Improved Machine for Inserting Pins or Rivets in Umbrella-Frames, ofwhich the following is a full, clear, and exact description' Thismachine is more especially intended for entering and also cutting therivets or pins used in making umbrella-frames.

Reference is to be'had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all thefigures.

Figure 1 is a sectionalside elevation of my invention. Fig. 2 is a frontelevation, showing the machine mounted upon the table T, show insection. Fig. 3 is sectional plan view, taken on the line at x of Fig.2, and showing the manner of holding the frame to receive the rivet.Fig. 4 is also a sectional plan view, taken on the line 3 y of Fig. 2and Fig. 5 is a detailed sectional elevation of the taken on the line zz of Fig. 2.

A represents the frame'ofthe machine which is cast with the neck a, head12, table 0, base d, and downwardly-projectihg flanges e e.

Pivoted at f in the neck a of the frame is the main operating bent leverB, by and through which the plunger E, knife-stock F, and feedrolls G Gare operated.

The forward end of the lever B is, by preference, enlarged to form thecircular -head B,

. shown in Figs. 2 and 5, and the plunger is made with the centralpassage or recess 9 to.

receive the said head, as shown in said figures, so that when the leveris moved upon its pivot the plunger will be I reciprocated in the ways hit formed in the head b of the frame in which it is held.

The lower end .of the plungerE is recessed, as shown at j, andscrew-tapped, as shown at j, Fig. 5, to receive the screw-threadedsleeve II, which is closed at its lower end by the cap it.

In the recess j is placed the coiled spring Z,

I which rests upon the upper end of the bolt J in the sleeve H. In thelower end of this bolt J is secured the centering point or tool m, whichprotrudes the proper distance from the orifice of the cap it. The springZ holds the bolt J down with considerable force upon the plunger,

' arm 0 of the bar K. Whenthe tool on comes Be it knownthat I, DANIEL M.REDMOND, of the city and county of Philadelphia and State ofPennsylvania, have invented a new' against .the pin-or rivet which isbeing in; serted in the frames, the spring I allows it to give, and theadvantage of this tool is that it centers the hole in the umbrella-framein the direct line of upward movement of the wire or rivet. 4

The arm 0 of the bar K enters the sleeve H through the slot p, andfromthence the bar extends upward along the rear face of the plungernear to the top of the plunger, where it is bent outward away from theplunger to form the arm 0, which arm is provided with the screw 10,which is adapted to come upon the upper end of the head I) of the frame,and may be adj usted. for regulating the distanoe of downward movementof the bolt J and tool m, according to the length of-the rivets or pinsbeing inserted, andthis screw coming in contact with the head I)prevents the centering-tool m from overlapping the wire T and wedging inthe hole.

The wire or rod T, from which the rivets or pins are cut, is fed upbetween'the knivesL L the proper distance to form the right length ofrivets at each operation of the lever B by the feed-rollers G G, betweenthe bearing-faces q q of which the wire is held as shown in Figs. 1 and2. These bearing-surfaces are by preference guttered, as shown in it,Figs. 2 and 4, to hold the wire against all danger of lateral movement.The wheel G is formed with the cogs aand is journaled in the'blocks I)b, which are placed in the slots 0 0 formed in the flanges e e of theframe. The wheel Gis formed with the cogs a, which mesh with the cogs aof the wheel G, and is formed also with the ratchet-teeth d, and thewheel is journaled in fixed bearings formed in the flanges e eof theframe, as shown at O in Fig. 4.

The series of cogs a a are made of considerable length, so that thewheel G may be adjusted to and from the wheel G to vary the contiguityof the bearing-surfaces q 9 of the wheels to suit wires or rods ofdifferent sizes. This adjustment is accomplished by the forked plate Nsecured to the front of the frame of the machine, the members 8 s ofwhich bear against the outer ends of the plates t it, formed or securedupon the axle O of the wheel G,

'as shown clearly in Fig. 4.

The plate N is attached loosely to the frame y the cam by means ofspring 1, as clearly shown 7' also carries the pawl S, (shown in Fig.1,)

by means of the screw 0, and is adapted to I have its lower end moved tosuit the size of the wire by screw f. 2

It will be understood that intermittent movement is imparted to thefeed-wheels G G for feeding thewire. This motion is produced by thepawl1ever P, which is operated from the main operating-lever B throughthe reciprocatingyoke Q and connecting-rodU, the pawl w of the leverbeing held in contact with the ratchet d of the wheel G by means of thespring w, shown clearly in Fig. 1. This pawllever P is fulcrumed onthepin or bolt 8, which passes through the block 1?, bolted between theflanges e e of the frame of the machine, and its rear end is pressedupward against the friction-roller g, 'placed upon the bolt 3' of theyoke Q, by the spring h, secured to the lower end of the block P, asshown in Figs. 1 and 2.

The yoke Q is forked, as shown, and is pivoted upon the bolt R, whichpasses through the flanges e e of the frame and the members 0- r of theyoke, as shown in Fig. 4. The bolt which is constantly held upwardagainst the cam V, (shown in Figs. 1 and 4,) by the coiled spring 76,(shown in the last-mentioned figure.) This cam V is placed upon the boltR, between the flanges e e of the frame of the machine, and when theyoke Q is reciprocatedis revolved intermittently upon the said bolt bythe pawl S for operating the knife-stock F, as hereinafter described. Inthis construction the yoke Q is reciprocated, as above mentioned, by themain operating-leverBthrough the connecting-rod U, and this movement ofthe yoke, besides giving intermittent rotary movement to the cam V, alsorocks the lever]? upon its pivot for imparting intermittent rotarymotion to the feed-wheels G G, as above mentioned, the roller 9 beingcarried forward by the forward movement of the yoke in the are of acircle, and coming in contact with the upper side or edge of the lever,as will be understood from Fig. 1.

The length of the connecting-rod U is made adjustable by means of thescrewthreaded coupling-rod a, which enters the internallyscrew-threadedcollar 7), as shown in Fig. 1, so that the movement of the yoke may bevaried for increasing or diminishing the feed of the rollers G G, ascircumstances require.

The cam V is formed with the series of deep notches s, the series oflips or outward proj ections, t, and the series of intermediate planesurfaces, '0, and the knife-stock F is pivoted in the throat F of thetable part c of the frame of the machine upon the pin f, and its rearend, '0, reaches back in the frame and over the cam, and is held incontact with the surface of in Fig. 1.

Thus constructed, the operation and use of the machine willbe asfollows: \Vhen the main operating-lever B is carried back, at or aboutthe time it reaches the limit of its backward movement, the rear end, 0,of the knife-stock will pass over one of the lips 15 of the cam and dropinto one of the deep notches .s. In this position the knife-stock willhold the knife L away from the edge of the stationary knife L, leaving afree passage for the upward movement of the rod or wire T. Upon the mainlever being carried forward, the rod T will be fed up'between the knivesby the movement of the feedrollers, and about the time the lever reachesthe limit of its forward movement,

the pawl Sv will be lifted by its spring into one of thedeep notches son the lower side of the cam. At this time the umbrella-frames y y (or.whatever is to receive the rivet or pin) are put together and placedover the upper end of the-rod or.wire T, as shown in Fig. 1. The leverBis now to be forced backward. This movement will simultaneously lowerthe plunger E and turn the cam V. The first movement of the cam willcause the rear end,

'12, of the knife-stockto be raised out of the deep notch s in which ithad dropped, and to rest upon one of the plain intermediate surfaces 1;of the cam. This will cause the knifestock to carry the knife L forwarda sufficient distance to firmly grasp the rod or wire T between it andthe edge of the stationary knife L. The rivets used in umbrella-framesbeing alwaysslightly larger than the holes in which they are to beplaced, the insertion of them by hand is slow and difficult. On theother hand, the tool m isv smaller thanthe rivet-holes, so that it maypass readily through them and enable the attendant to hold theumbrella-frames steadily over the wire as the latter is pressed upthrough them. The guide XV- is a valuable auxiliary, but it is notsufficient to prevent the frames from wabbling. Hencelhavefound itnecessary to employ the centering-tool m. grasping the wire or rod theplunger E descends and performs its workthat of pressing or, forcing theumbrella-frames (or other object) upon the end of the wire or rod.- Atthis time the point an serves as a centeringtool for entering theorifices in the parts of the frames, and brings them in line over theupper end of the rod-or wire. the plunger completes it descent one ofthe lips or projections t of the cam V will have passed under the end 1)of the knife-stock, causing the same to be raised and the upper end ofthe stock to be carried forward, causing the knives to completely severthe rivet or pin from the wire or rod. The rear end of the knife-stocknow drops into the next deep notch of the cam, putting the parts of themachine in their original position ready for re peating the operation.

The stationary knife L maybe held in the table 0 in any suitable manner.It is by preference secured by means of screws, rivets, or other meansupon the plate WV, which is fitted in a dovetailed recess formed in thesaid table, as shown in Figs. 1-, 2, and 3, and this plate is madeadjustable in said recess by the screw 11,

At the time.

While the knives are thus IIO for adjusting the knife, as clearly shownin said figures.

The knife L is, by preference, held in place in the upper end of theknife-stock F by means of a dovetailed slot formed in the upper end ofthe said stock, as shown in Fig. 3, and this knife is made adjustable bymeans of the screw a, as shown clearly in Figs. 1 and 3.

W, Figs. 2 and 3, represents a guidefinger secured in the bracket M,bolted to one side of the table 0 of the frame, for assisting theattendant in holding the frames to be riveted upon the upper end of thewire, as indicated in Fig. 3. Against the guide-finger WV the attendantholds the frames which are to receive the pins or rivets, so as tosteady them upon the upper end of the wire. This guide-finger W ispivoted and a spring placed under it, as shown in Fig. 2, so that it maymove downwardly when the plunger E comes down upon it; and M is aguide-plate, secured by means of screws to the front face of theknife-stock F, in the throat F of the frame, for guiding the upper endof the wire T, as shown in Fig. 1, as it is fed upward between theknives.

The lever B may be operated by foot, steam, or other power.
